NATURAL-GAS BURNER FOR HEATING STOVES, FURNACES, BOILERS, do.

SPECIFICATION forming part of Letters Patent No. 468,155, dated February 2, 1892. Application filed J'uly 13, 1891. Serial No. 399,286. (No model.)

To all whom if; may concern:

Be it known that I, MICHAEL J. ORTELLY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Natural-Gas Burners for Heating Stoves, Furnaces, Boilers, rbc.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a combination 0f natural-gas burners arranged so as to allow of their working closer together or farther apart in any stove, range, boiler, furnace, &c., to cover more or less heating-surface by means of adjustable links in connection with the burners.

lt also relates to the simple construction of the burners and mixers, all as fully hereinafter set forth.

In the drawings, Figure 1 is a top plan; Fig. :2, a side elevation of t-he whole device, partly in section; Fig. 3, a top plan of one adjusting-link removed.

A A represent the gas-supply pipes, screwing into joints A A on ashort screw-threaded pipe A", which screws into a cross-piece a in the lower part of the gas and air chamber B, called the mixer, delivering the gas therein. These mixers are hollow and preferably bell-shaped, screwing onto the bottom of the mixing-tube C, the tube then passing through a round hole (1 in an adjusting link or arm D, held therein by the collar c of the lower cupdisk E of the burner, which screws on the top of the tube C, as shown in Fig. 2. A second cup-disk E', in a reverse position to the other, sets over the latter, and is adjusted up or down by screwing the stem in a cross-piece d in the lower cup. A small set-screw c is used to set it, if desired, the adjustment being to diminish or increase the space between the disks to regulate the flame. This simple construction is entirely successful and does away with specially prepared burners, and the tubes O will serve as burners under large boilers. The flow of air is regulated in the mixers Bby a dat disk G, provided with internal threads and screwing on the gas-pipe A" below the bottom of the bell, and by turning thereon gives a greater or less space g for the inward iiow of air as may be required for a proper mixing with the gas therein and in tube O. V

he middle burner is nearly flat and may be square, oblong, or triangular in shape, and is usually closed on all sides except that which faces the oven or water-back in a stove or range. It is composed of two plates II H', concaved slightly inside to ber, and the ends arecemented together or fastened by bolts or screws, the flames coming through the single opening, as shown by the arrows in Figs. 1 and 2', the space being just sufiicient (flat but wide) t0 give a strong heat where most needed. The other two burners E E are adjusted and held links or arms D on top of the burner ll Il and u nder the usual stove-holes in a range, tbc. One link sits partly on top of the other, and both are held by the nut i, screwing on the boss 71., as in Figs. 1 and 2.

Into the under side of thelower plate ll is screwed a mixing-tube O and mixing-bell l, similar to the others described.

The dat links D D act not only as holders of the burners E E', but allow their adjustment longitudinally or laterally, so that the same burners can be iitted to different stoves, ranges, furnaces, rbc., instead of having several different sizes manufactured, and when once adjusted in place it will not be necessary to change unless to another stone, tbc.

Simplicity of construction and efficiency in working are the great features of this device tl'iroughout. rlhe three burners, as shown, form the necessary combination for any stove, furnace, range, ttc., that is supplied with natural gas.

l claiml.. In a gas-fuel stove, range, or furnace, the combination of the mixing-tubes O, provided at their upper ends with the concave burners E E', adjustable thereon,the air and gas receiving chambers B on the lower end of tube C, and the central oblong burner H H', provided with the air-disk G, adjustable on its gas-receiving pipe A all arranged tomake a gas-chamby flat connecting IOO gether for conjointv work, subsfcantially as longitudinal or lateral adjustment by the specified. boss h and nut; z' on top of the central burner, 2.
